Comparative wood anatomy of Taxaceae

Australian Systematic Botany, 2015
Comparative wood anatomy of Taxaceae s.l. was examined to elucidate the differences in wood features among genera. In total, 25 samples, comprising three varieties and seven species from five genera (Pseudotaxus was not included), were examined. Sliding microtome, wood maceration and scanning electron microscopy methods were used for the study.

Ultrastructural features of megasporogenesis inTorreya nucifera (Taxaceae)

Plant Systematics and Evolution, 1996
In megasporogenesis ofTorreya nucifera (Taxaceae) more than one product of meiosis can start to germinate, a process previously observed inTaxus. Ultrastructural analysis ofT. nucifera revealed that this behaviour is cytologically determined by the presence of a transfer cell type wall-membrane apparatus and by the presence of uncommonly complex ...

RNAseq‐based phylogenetic reconstruction of Taxaceae and Cephalotaxaceae

Cladistics, 2018
AbstractTaxaceae and Cephalotaxaceae are the two economically important conifer families. Over the years there has been much controversy over the issue of merging these families. The position of Amentotaxus and Torreya is also ambiguous. Some authors consider them closer to Taxaceae while others deemed them to fit within Cephalotaxaceae.

The phylogenetic position of taxaceae based on 18S rRNA sequences

Journal of Molecular Evolution, 1993
The evolutionary position of the yew family, Taxaceae, has been very controversial. Some plant taxonomists strongly advocate excluding Taxaceae from the conifer order and raising its taxonomic status to a new order or even class because of its absence of seed cones, contrary to the case in the majority of conifers.

The complete chloroplast genome of Torreya fargesii (Taxaceae)

Mitochondrial DNA Part A, 2015
The complete chloroplast genome sequence of Torreya fargesii (Taxaceae), a relic plant endemic to China, is presented in this study. The genome is 137 075 bp in length, with 35.47% average GC content. One copy of the large inverted repeats is lost from this genome. The T. fargesii chloroplast genome encodes 118 unique genes, in which trnI-CAU, trnQ-UUG,

Taxonomic study on Pseudotaxus (Taxaceae)

Acta Phytotaxonomica Sinica, 2007
Two specific names, viz. Pseudotaxus chienii (Cheng) Cheng and P. liana J. Silba, were published within Pseudotaxus and leaf width was considered to be discontinuous between the two species. Width of leaf blades of herbarium specimen was measured and analyzed statistically with student’s t test and XY PLOT. Though a significant difference of leaf width

The complete chloroplast genome sequence of Amentotaxus argotaenia (Taxaceae)

Mitochondrial DNA Part A, 2015
The complete chloroplast genome sequence of Amentotaxus argotaenia was determined in this study. The genome is 136 657 bp in length and lacks one inverted repeat region. The overall GC content of the genome is 35.85% (protein-coding genes, 36.90%; tRNA genes, 53.31%; rRNA genes, 52.99%; introns, 36.10%; intergenic spacers, 31.03%). The A.
